Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof, and a rear elevational view is an upside-down image of the front elevational view; FIG. 2 is also a bottom plan view, and a top plan view is an upside- down image of the bottom plan view;

FIG. 3 is a left side view thereof, and a right side view is a mirror image of the left side view; and,

FIG. 4 is an enlarged fragmentary view from upper 4-4 to lower 4-4 in FIG. 2.

The broken lines defining the side wall illustrate environmental subject matter only and form no part of the claimed design. The dash-dot-dash broken lines define the boundary of the tire tread and form no part of the claimed design. Surface shading stippling form no part of the claimed design. 

CLAIM The ornamental design for a tire tread, as shown and described.
